Description

inkjet printing module

technical field

The invention relates to an inkjet printing module, in particular to an inkjet printing module suitable for page width inkjet printers.

Background technique

The carrying mechanism of the printing platform of a common printer can be roughly divided into two types. One is to use a conveying device to scan and move the ink cartridge arranged on the carrying mechanism along a horizontal axis, and the paper to be printed Driven by the paper feeding mechanism, it passes under the ink cartridge along a longitudinal axis, and the ink in the ink cartridge is sprayed onto the surface of the paper by the inkjet head to complete the printing operation.

Another type of printing platform has a fixed bearing mechanism, using the nozzle array of the printing platform whose width is greater than or equal to the width of the paper to be printed, to directly print the paper passing under the nozzle array. This printing mode is called page printing. Wide (page-width array) printing is to install and arrange several inkjet chips on the bottom of the supporting mechanism of the printing platform, which can achieve certain convenience and efficiency in the printing process, but still has the following shortcomings to be improved:

1. Since several inkjet chips are installed and arranged at the bottom of the bearing mechanism of the printing platform, if one of the inkjet chips is damaged, it will affect the overall printing quality, and each inkjet chip cannot be replaced separately, and it needs to be repaired. Group printing platform to do replacement.

2. In order to deliver the ink to the ink chambers connected to the inkjet chips, the page-width printing platform needs to be equipped with a complicated ink supply channel design, which will increase the design and manufacturing costs.

3. In order to manufacture a page-wide printing platform, it is necessary to install and arrange the inkjet chips one by one at the bottom of the supporting mechanism. In this way, the installation and layout of the control circuit requires a more complicated manufacturing process, which will inevitably increase the manufacturing man-hours and manufacturing costs.

Therefore, how to develop an inkjet printing module that can improve the above-mentioned deficiencies of the known technology and solve the problem that the entire printing platform needs to be updated in the known technology is an urgent problem to be solved at present.
